No matter where you live, you can measure the main
target species with just the one tool - REEF RULER

REEF RULER is not available for this region.

REEF RULER is a 'guide only' tool and is not recommended for commercial use. Please ensure the REEF RULER is straight on each plane and not distorted. Checks of each calliper should be made to ensure the guide does not measure under the stated size. Minimum sizes of species are subject to change. Check with relevant State Laws to ensure your REEF RULER is compliant.
